When we remodeled our bedroom we moved our TiVo into the closet. Running the HDMI cable to the TV from the TiVo was easy - figuring out how to get the remote was a little harder. We have aTiVoSlide remote control which works via Bluetooth: a Bluetooth receiver connects to the TiVo via USB cable. I needed to be able to get the receiver out of the closet and into the main bedroom, ideally behind the television. The maximum length of a USB cable is 10-15 feet, depending on the device, which was too short to reach from the TiVo to the television.
The first solution I tried was a Tripp Lite repeater cable, which is unpowered. The Bluetooth receiver appeared to work just fine with it: a blue light on it illuminated and the light blinked in response to button presses on the remote, just as it should. The commands, however, were not received by the TiVo. The repeater cable was able to boost the signal enough to reach from the TiVo to the receiver, but the receiver didn't have enough strength to send the commands back to the TiVo through the cable.
While I looked for another solution I connected the receiver to a 6' long USB extension cable, just to get the receiver out of the closet so it could receive commands from the remote. This worked but not very well. The commands were received by the TiVo but there was a delay so the response was very laggy. In addition, not all the commands were received by the TiVo which made it very hard to control the DVR.
Clearly a powered solution was required. Though this product didn't have any reviews when I ordered it I didn't have many options. I've used Cables Unlimited cables before so at least I was familiar with the brand.
Amazon's product page is a little light on information for this product and there are a couple of critical pieces of information which should be on the page. The product page at the Cables Unlimited site has more information. First, this extender is only USB 1.1 compliant, not USB 2.0 compliant. Second, only one device can be connected to this extender so putting a hub at the end of it won't work (according to Cables Unlimited, at least).
This extender couldn't be any easier to set up, which is good because the instructions consist of a single diagram. There are 3 pieces to this product: the sending and receiving units and a power supply. The sending unit is a small box labeled "local". It has a USB connection that plugs into your computer (or TiVo in my case) and a port for an Ethernet cable, so it has a male USB and a female Ethernet connection. The receiving unit is labeled "remote" and has a port to plug the remote USB device into (in my case the TiVo Bluetooth receiver) and an Ethernet port, so it has a female USB and a female Ethernet connection. The power supply plugs into the remote end as well.
I plugged the "local" box into the TiVo and connected a 35' Ethernet cable to it. Into the remote end I plugged the other end of the Ethernet cable, the power supply, and the Bluetooth receiver. That was it. The receiver came to life, the TiVo recognized it, and everything just worked. Not only did the remote work, it worked great. There was no lag, no dropped commands. It was as if the Bluetooth receiver was connected directly to the TiVo. I've got no complaints about how well this extender works or how easy it is to install.
My only complaint is the power supply. It doesn't plug all the way into the "remote" box - about 1/4" of the plug is left exposed. Where I have the "remote" box set up this isn't a problem but it could be an issue depending on where it's set up. The USB cable doesn't fit all the way into the "remote" box either. Thatt's just sloppy design so I docked the product a star. I've uploaded a picture to show the gaps.
Overall, though, this extender works great. Powering the remote box really made the difference. As responsive as the TiVo remote is I think this extender could be used for mouse, keyboard, or even a gaming controller, as long as they only need a USB 1.1 connection.

Fire-i Webcam Firewire Digital Camera By Unibrain Review

With good lighting, this Firewire camera will perform as expected. I bought it because I had a couple of Firewire ports without use and the wider availability of USB webcams would force me to buy a USB port multiplier. My main complaint with this camera is that the provided Firewire 400 cable will tip it over since the tripod is quite flimsy. It should also include a base to place it on top of a flat monitor, a better location for the camera.

IPEVO Point 2 View USB Camera Review

Got this for my classroom after seeing it used with an ipad. Setup is very easy and resolution was as good or better than the ELMO document readers used at school. Also highly recommended for teachers sharing specific book pages or excerpts, anchor writing work, and images from an individual book. And those beetles on a screen or smartboard!

Slide Scanner Gets History Out of the Shoebox Review

Slide Scanner Gets History Out of the Shoebox

I purchased this product to digitize a number of color slides and film negatives to PNE or JPEG image formats. Even though the scanner's imaging CMOS lens resolution is listed as 48 bits, the scanned image quality was very poor (grainy, uneven, out of focus). The editing software included with the package was also rudimentary and not very intuitive. I would not recommend this product; unfortunately, it was a waste of money.
